Description
Technical field
The present invention relates to the material of a kind of pavement crack repair, specifically a kind of environment-friendly type road-surface heating type sealant material
And preparation method and application.
Background technology
At present, highway in China construction is also continuing expansion construction scale through development for many years, especially highway.So
And, perplex Domestic & Overseas Asphalt Pavement problem of Cracking and be well solved the most not yet.The existence in gap can cause road
The local failures such as internal frost heave, the corrosion of mineral aggregate and peeling, have a strong impact on stationarity and the safety of driving the most at last, and
The service life on road surface can be substantially reduced.The fluid sealant wide material sources of current domestic employing, quality is uneven, and using effect is not
Ideal to the greatest extent, because being limited by characteristics such as the low temperature cold fragility of gap-grouting material and hot mastications, the crack after repairing can be with gas
The change of temperature is ftractureed again through the surface layer harmomegathus of 1 year.Particularly cryogenic property is the most poor, and a lot of fluid sealant one is to winter
I.e. with sides of fracture tear, lose waterproof effect, have become as restriction filling cut of asphaltum road surface technology development one crucial because of
Element.The existence of this problem, has increased the weight of workload and material cost that maintenance of surface is safeguarded.
The Chinese patent of Publication No. CN105199666A, discloses a kind of road that can be applicable to various material road surface and splits
The Road sealant that seam is repaired produces and construction technology；Main is the matrix pitch of 29% by mass percent, 15% thin
Rubber powder, the fossil meal of 45%, the SBS modified pitch of 0.4%, the butadiene-styrene rubber rubber powder of 0.4%, the activating agent of 0.1%,
The viscosifier of 0.1% and the diesel oil composition of 10%；For Colophonium, Concrete Highway, highway, high-grade highway, city public affairs
The cementation of fissures of the bituminous paving such as road, airfield runway is repaired and the joint seal reparation of cement concrete pavement.
Summary of the invention
It is contemplated that according to different regions and different weather conditions and pavement crack feature, want in particular according to environmental protection
Ask, select suitable fluid sealant as the material of pavement crack repair.
Merge with bituminous paving infiltration it addition, the present invention realizes at high temperature fluid sealant, there is sufficient elasticity, the most excessive
Or viscous tire；Produce high cohesive force after cooling, and rely on stronger elasticity, with crack harmomegathus, elastic deformation occurs, particularly exist
Remain its sealing function winter.
The present invention specifically the technical scheme is that
A kind of environment-friendly type road-surface heating type sealant material, is characterized in that, uses and includes that the raw material of following weight portion is made:
Wherein, described petroleum asphalt penetration is 100-200, and described SBS modifier is s-B-S
Block copolymer, described SBR modifying agent is polystyrenebutadienes copolymer, and described phase solvent (compatilizer) is naphthenic rubber
Oil, described inserts is sodium bentonite.
In the present invention, the polyester fiber used its be mainly composed of polyethylene terephthalate, described lignin
Fiber preferred natural timber organic fiber, the Colophonium that described natural rock asphalt uses marque to be Qing Chuan NES.
Conventional cross-linking agent in state of the art selected by the cross-linking agent of the present invention.
The preparation method of a kind of environment-friendly type road-surface heating type sealant material, is characterized in that, comprise the steps:
1) according to proportioning of the present invention, bi tumenf orr oad is preheated to 180-200 DEG C and adds material-compound tank, continuously stirred state
Lower addition SBS modifier, the full and uniform mixing of SBR modifying agent, swelling 10 minutes；
2) shear grinding 2-3 time through colloid mill, make modified grain fineness reach below 5 μm, be delivered to grow tank and add
Cross-linking agent, keeps 180-200 DEG C of circulation, stirring to grow 3-5h, forms the high temperature premix material with stabilising system；
3) premix material is delivered to premixing tank, in premixing tank, is sequentially added into waste tire rubber under continuously stirred state
Powder, natural rock asphalt, phase solvent, polyester fiber, lignin fibre are warming up to and keep 180-200 DEG C of stirring to grow 1-2h to mixed
After closing uniformly, add sodium bentonite under continuously stirred state and be warming up to and keep 180-200 DEG C of stirring to grow 1-2h to mixed
Close uniformly；
4) it is delivered to hot mixture in premixing tank in low temperature kneader again be cooled to and keep 150-170 DEG C to mediate 1-
2h to after fully reaction, is cooled to 130-140 DEG C of extruded machine extrusion and weighs vanning molding, make environment-friendly type road-surface heating type close
Adhesive material.
The application of a kind of environment-friendly type road-surface heating type sealant material, is characterized in that, described sealant material is for common
The sealing reparation of highway, highway, airfield runway crack and seam.
Compared with prior art, the invention have the advantage that
1) due to the naphthenic rubber oil added, it is a kind of material that can meet exported product environmental requirement, substitutes existing
Aromatic naphtha in product, environment protection significance is very big；
2), during NES natural rock asphalt in Qing Chuan results from special rock fracture, suffered pressure and temperature conditions are than it
His bitumen is high, therefore extent of polymerization is the highest, and molecular weight is very big, and softening point is higher；
3) polyester fiber and the Colophonium being both oil product have extremely strong adsorptivity, have in media as well good adsorptivity and
Dispersibility；Lignin fibre has good toughness, dispersibility and chemical stability, has the most outstanding thickening cracking resistance；
4) sodium bentonite Heat stability is good, has stronger plasticity, bloating tendency, caking property, adsorptivity, catalytic, touches
Degeneration, suspension and cation commutativity etc..
5) present invention has cohesive, low temperature flexibility, heat stability, anti-embeddability and the resistance to ag(e)ing of excellence, can be extensive
It is applied to crack and the sealing reparations of seam such as common road, highway, airfield runway.
